Monit初期インストール
6627 ワード
monitは強力なシステム状態、プロセス、ファイル、ディレクトリ、デバイスの監視ソフトウェアであり、*nixプラットフォームに使用され、すでに掛けられたプログラムを自動的に再起動することができ、nginx、apache、mysql、cpu占有率など、システムの重要なプロセスとリソースを監視するのに非常に適しています.一方、Pythonプロセスのモニタリング管理は、supervisorが一般的であり、後で別途紹介します.
monitのインストール、構成、起動について説明します.
インストール
Step 1 M/Monitライブラリの作成
/usr/local/mysql/bin/mysqladmin create mmonit -uUSER -pPASSWD
/usr/local/mysql/bin/mysql -f -h localhost -uUSER -pPASSWD -e "use mysql; grant all privileges on mmonit.* to mmonit@localhost identified by 'mmonit';"
/usr/local/mysql/bin/mysql -f -h localhost -uUSER -pPASSWD -e "use mysql; flush privileges;"
データベースの表示
mysql> show databases;+--------------------+| Database |+--------------------+| mmonit | | mysql | | test | +--------------------+
Step 2 tarパッケージを取り付ける
monitソースパッケージのダウンロードhttp://mmonit.com/download/
tar zxf monit-5.1.1.tar.gz
cd monit-5.1.1
/monit-5.1.1]# ./configure
/monit-5.1.1]# gmake
